- The aim of this study was to determine intra- and interobserver reliability in 3D intrastomal ultrasound imaging of parastomal hernia and protrusion. A total of 40 patients were investigated. Two or three physicians evaluated the images twice, 1 month apart. Inter-observer agreement was 72 % with a kappa value 0.59. For the last 10 patients there was an agreement of 80 % with a kappa value of 0.70. Intraobserver agreement was 80 % for one observer and 95 % for the other. The learning curve levelled out at around 30 patients. Considering the learning curve of 30 patients, 3D intrastomal ultrasound is a reliable investigation method. 3D intrastomal ultrasonography has the potential to be the investigation of choice to differentiate between a bulge, a hernia, or a protrusion.

- A considerable proportion of stoma patients are disabled for various reasons and are elderly. To be able to dress their stoma themselves is of crucial importance for their integrity and social life. This study evaluates a novel stomal dressing system based on a magnetic connector-the Easy-X system. Twenty patients (8 women, mean age of 40-89 years) with a well-functioning colostomy tested the Easy-X system for 6 weeks. The system was judged by the patients using a multiple choice scale, and by the stoma nurses using a 10-grade VAS. Eighteen of 20 patients completed the trial. Ten patients rated the Easy-X as better than their ordinary system, 3 as equal to and 4 deemed it inferior. Despite this, only three were prepared to change to the Easy-X system. Eleven of 18 patients experienced discomfort with the new adhesive plate. Three patients suffered leakage less often and five patients more often than with their ordinary system. Stoma nurse ratings were available for 14 patients. Their evaluation of the magnetic connector in the Easy-X system was positive in eight cases, neutral in one case and negative in three cases. Global impression ratings were 3 positive, 3 negative and 5 neutral. The Easy-X system showed potential advantages over conventional stomal dressing systems, but the system must be improved in terms of a varied assortment of dressing products enabling individual fitting before a larger trial can be carried out on disabled patients. Furthermore, the increased use of metal has to be handled with an ecologic recycling system. A new stomal dressing system with a magnetic connector has potential advantages over conventional stomal dressings for disabled persons.

- PURPOSE: Girdles and abdominal binders may reduce pain and stabilize the abdominal wall after laparotomy, but a risk for increased intra-abdominal pressure and decreased lung function is also hypothesized. The aim of this study was to investigate the effect of an abdominal girdle after midline laparotomy in a randomized controlled trial. METHODS: Twenty-three patients undergoing laparotomy were randomized to wear an elastic girdle postoperatively and 25 were randomized to no girdle. Pulmonary function was evaluated with; forced vital capacity (FVC), forced expiratory volume during one second (FEV1), peak expiratory flow (PEF), and cough PEF. Pain was recorded using a visual analog scale (VAS). All patients completed the ventral hernia pain questionnaire (VHPQ) before surgery and at the end of the study. Intra-abdominal pressure was measured via an indwelling urinary catheter. Wound healing was assessed from photographs. RESULTS: FVC, FEV1, PEF, and cough PEF were reduced by about 30 % after surgery, but there were no differences between patients with or without a girdle (ANOVA). Intra-abdominal pressure and wound healing were the same in both groups. Pain was significantly lower on day 5 in the girdle group (p = 0.004). CONCLUSIONS: An individually fitted elastic girdle used after midline laparotomy was found to be safe, as this did not affect lung function, coughing, intra-abdominal pressure, or wound healing. The immediate decline in lung function after surgery is restrictive and due to anesthesia and the surgical procedure. Pain was significantly decreased in the girdle group. The study is registered at ClinicalTrials.gov, number NCT01517217.

- PURPOSE: Since there are no reliable investigative tools for imaging parastomal hernia, new techniques are needed. The aim of this study was to assess the validity of intrastomal three-dimensional ultrasonography (3D) as an alternative to CT scanning for the assessment of stomal complaints.METHOD: Twenty patients with stomal complaints, indicating surgery, were examined preoperatively with a CT scan in the supine position and 3D intrastomal ultrasonography in the supine and erect positions. Comparison with findings at surgery, considered to be the true state, was made.RESULTS: Both imaging methods, 3D ultrasonography and CT scanning, showed high sensitivity (ultrasound 15/18, CT scan 15/18) and specificity (ultrasound 2/2, CT scan 1/2) when judged by a dedicated radiologist. Corresponding values for interpretation of CT scans in routine clinical practice was for sensitivity 17/18 and for specificity 1/2.CONCLUSION: 3D ultrasonography has a high validity and is a promising alternative to CT scanning in the supine position to distinguish a bulge from a parastomal hernia.

Morbidity related to defunctioning loop ileostomy in low anterior resection
- 2012
-

- Aim A defunctioning loop ileostomy in low anterior resection reduces the incidence and morbidity of an anastomotic leakage, but complications related to the stoma may occur. We explored stoma-associated complications during the stoma period and after stoma reversal. Methods A retrospective analysis of rectal cancer patients operated with low anterior resection and a defunctioning loop ileostomy at Helsingborg Hospital and Malmo University Hospital from January 2007 to June 2009 was undertaken. Results Ninety-two patients were included, of whom 82 (89 %) underwent stoma reversal. The median stoma period was 6.2 +/- 3.2 months. Sixty-six percent of the patients suffered from minor or major stoma-associated morbidity. The complication rate was significantly related to the stoma time (p < 0.01). Twenty-nine percent (27/92) had at least one episode of dehydration, leading to readmittance in half of the cases. Elderly patients were more prone to develop dehydration. Dehydration most commonly occurred early in the postoperative period (mean, 5.8 weeks). The mean hospital stay for stoma reversal was 6.5 +/- 4.0 days. Forty percent (33/82) had some complication associated with the reversal. Conclusion This study indicates high morbidity associated with defunctioning loop ileostomy. Our data suggest that the stoma time should be limited to reduce complications. Monitoring and early stoma reversal should be considered in elderly patients. Furthermore, stoma reversal is not uneventful, and more studies are needed to address how to minimize complications.

- PURPOSE: Abdominoperineal resection (APR) for rectal cancer results in a permanent colostomy. As a consequence of a recent change in operative technique from standard (S-APR) to extralevator resection (E-APR), the perineal part of the procedure is now performed with the patient in a prone jackknife position. The impact of this change on stoma function is unknown. The aim was to determine stoma-related complications and the individual patient experience of a stoma. METHODS: Consecutive patients with rectal cancer operated on with APR in one institution in 2004 to 2009 were included. Recurrent cancer, palliative procedures, pre-existing stoma and patients not alive at the start of the study were excluded. Data were collected from hospital records and the national colorectal cancer registry. A questionnaire was sent out to patients. The median follow-up was 44months (13-84) after primary surgery. RESULTS: Ninety-six patients were alive in February 2011. Seventy seven agreed to participate. Sixty-nine patients (90%) returned the questionnaire. Stoma necrosis was more common for E-APR, 34% vs. 10%, but bandaging problems and low stoma height were more common for S-APR. There were no differences in the patients' experience of stoma function. In all, 35% of the patients felt dirty and unclean, but 90% felt that they had a full life and could engage in leisure activities of their choice. CONCLUSIONS: This exploratory study indicates no difference in stoma function after 1year between S-APR and E-APR. Over 90% of the patients accept their stoma, but our study indicates that more information and support for patients are warranted.

- BACKGROUND: Colonic obstruction is a common complication to colorectal cancer and surgical treatment is associated with high morbidity and mortality. Stenting has emerged as an alternative to surgery. The aim of this study was to compare short-term morbidity, mortality and hospital stay between treatment with self-expandable metallic stent and emergency surgery performed at our department during a 5-year period in a non-randomized setting. METHODS: Patients with colonic obstruction due to rectal or colon cancer referred to the Endoscopic Unit or Surgical Department for insertion of a colonic stent between 1 August 2003 and 1 August 2008 were prospectively registered and followed (n=112). A control group was identified using the hospital records of operations with the International Classification Code-10 (ICD-10) for bowel obstruction and colorectal cancer (n=60). Age, gender, indication, preoperative investigations, surgical procedure, complications and procedure-related mortality were registered. Patients were followed in accordance with local guidelines. RESULTS: The complication rate was similar in the two groups, although there was a trend toward a higher number of severe complications in the surgical group. The hospital stay was significantly lower in the stent group, median of 4 vs. 9days (p<0.0001). The procedure-related mortality was lower in the stent group; 7% vs. 20% (p<0.05). CONCLUSIONS: Stenting can be safely performed with lower or similar complication rate and lower mortality rate compared to surgery and results in significantly shorter hospital stay. The results support stenting as the treatment of choice in patients with acute colonic obstruction, especially in disseminated disease.

- Background Interleukin-8 (IL-8) also referred to as CXCL8, a member of the CXC chemokine family that attracts neutrophils and other leukocytes, has been associated with cancer. Angiogenesis is a prime regulator of tumour expansion and data support that IL-8 is a potent angiogenic factor. Epigenomic instability has been postulated to play a role for the development of multiple neoplasias including colorectal cancer (CRC). DNA methylation of cytosine residues in CpG dinucleotides leads to transcriptional silencing of associated genes.Method In this study, we comparatively analysed the protein expression of IL-8 in plasma, tumour and paired normal tissue and methylation status of the IL-8 gene to evaluate its impact on CRC.Results Collectively, by using Luminex technology, we noted a significantly higher IL-8 level in cancer tissue compared to paired normal tissue and that CRC patients exhibit significantly higher plasma levels than healthy controls. Analysed by methylation-specific polymerase chain reaction, we detected IL-8 hypomethylation in 64% of the cancerous tissue cases but no hypomethylation was found in paired normal tissue. We noted that the CRC patients with IL-8 hypomethylation revealed a significant higher level of IL-8 protein in cancerous tissue, which tended to be associated with distant metastasis. We also observed that patients with distant metastasis showed a significantly higher plasma level of IL-8 in relation to patients without distant metastasis.Conclusion Our results suggest that the predominance of high plasma levels of IL-8 in patients with distant metastasis in combination with the hypomethylation of the IL-8 promoter region might be a useful marker of the disease advancement.

Population-based screening for colorectal cancer with faecal occult blood test-do we really have enough evidence?
- 2010

Tidskriftsartikel (refereegranskat)abstract
- INTRODUCTION: Population-based randomised controlled trials (RCT) have shown that invitation to biennial screening with faecal occult blood testing (FOBT) during 10 or more years reduced colorectal cancer-specific mortality. These results have stimulated plans to introduce mass screening in various countries; however, none of these trials has been able to show any reduction of total mortality, which should be expected with reduced disease-specific mortality in a RCT. METHODS: The aim of this review is to analyse, in more detail, the findings in these trials. The results of the trials have, in this review, been systematised and discussed in the context of potential bias, validity and effectiveness. RESULTS: It is found that the reduced cancer-specific mortality is modest and that the clinical significance may be discussed. The number of persons needed to be invited for multiple screening rounds to avoid one death in colorectal cancer (CRC) is high, ranging from about 600 to 1,200. A remarkable finding is that only one fourth of the carcinomas in those invited to the screening were actually detected by this intervention. The absence of reduced total mortality in all series is a serious problem and evokes questions about the validity in determination of cause of death. None of these trials showed any effect on incidence of CRC by removal of precancerous adenomas. CONCLUSIONS: It seems reasonable to conclude that the scientific evidence to support introduction of population-based screening programmes with FOBT appears not yet strong enough. In addition, harm/benefit and cost/effectiveness ratios are not well determined.

- PURPOSE: In a register study, the risk of anastomotic leakage correlated to the choice of circular stapling device with a 4% difference between the two brands used. Based on those data, a randomised multicentre study was started to explore the risk of an anastomotic leakage based upon the surgical device. METHODS: Patients above 18 years with a rectal cancer, able to give informed consent, and scheduled for an anterior resection were eligible for the study. Perioperative randomisation was to Ethicon™ PROXIMATE™ ILS™ or Autosuture™ Premium Plus CEEA™. Anastomotic leakage was defined as a clinically manifest leak. RESULTS: Five hundred twenty-nine patients were randomised (58% male). A leak occurred in 8.3%. The anastomoses created by PROXIMATE™ ILS™ leaked in 25/265 (9.4%) anastomoses, and the Premium Plus CEEA™ leaked in 19/260 (7.3%), p = .419. CONCLUSION: No difference in the leak rate could be revealed. Several centres replaced one of the staplers by a new product, and the study was ended before the stipulated number of patients was reached. In the future, surgical devices may have to prove superiority in randomised trials or be monitored in quality registers before they can be introduced into day to day surgical practice.
